Mediastinal lipomatosis as a cause of low voltage complexes on electrocardiogram and widened mediastinum: A case report

摘要

Background Mediastinal widening is a common finding on chest radiograph, and can be caused by numerous conditions. Most of these diseases have grave prognosis if accompanied by chest pain, and require immediate attention. However, mediastinal lipomatosis is a very benign condition caused by deposition of adipose tissue in the mediastinum. Case presentation We present a case of a morbidly obese female patient who presented to emergency department with a fall. She had mediastinal widening on chest radiograph, and borderline low voltage on electrocardiogram. On computed tomography, mediastinal lipomatosis was evident. Conclusion Obesity is a major epidemic in United States, and can lead to deposition of fat in the chest. Mediastinal lipomatosis is very benign condition, which rarely causes grave consequences.
